Pink knit Sweater XS

Pink knit Sweater XS (165/88A) Loose knit on upper chest and back. The tighter knit starts down from approx where the tops of most bras would start to show through. See photos for material (used google translate to read label) This fits me and I wear XS/S. It does feel like it could be a petite fit. Length works nicely with a pant or jeans with a high waist. Half sleeve arms (9” from shoulder). For pit to pit measurements I would go by the width of bottom of the sweater - Approx 15.25” The extra width in arm pit area is part of the style and not accurate for sizing B-124
